This Arduino library created will allow you to control various functions of your radio via an Arduino micro-controller through the use of “Computer Aided Transceiver” (CAT) functions. Although the CAT command byte definitions are aimed at a Yaesu FT-897D, many of the functions should work along the FT-8*7 platform with little or no need for modification.
Requirements: Arduino 1.8.x FT897D library CAT control interface from radio
GND -> Arduino GND
TX -> Arduino pin 2 (can be changed in library)
RX -> Arduino pin 3 (can be changed in library)
Command Set:
To use the library functions, call them using the identifier you have chosen (ie. “radio” as the above example suggests). A list of the functions is as follows:
lock on / off = radio.lock(true / false);
PTT on / off = radio.PTT(true / false);
Set frequency = radio.setFreq( desired frequency – no decimals );
Set operating mode = radio.setMode( mode name – eg. usb );
Clarifier on / off = radio.clar( true / false );
Clarifier frequency = radio.clarFreq( desired frequency – again, no decimals );
VFO A / B swapping = radio.switchVFO();
Split operation on / off = radio.split( true / false );
Repeater offset direction (+, -, simplex) = radio.rptrOffset( +, -, or s );
Repeater offset frequency = radio.rptrOffsetFreq( offset frequench in kHz );
CTCSS / DCS on / off = radio.squelch( DCS or TEN );
CTCSS tone / DCS code = radio.squelchFreq( frequency, T or D );
Read TX status = radio.chkTX(); – returns true / false
Read RX frequency & mode = radio.getFreqMode();
Installation:
To install this library, simply extract the archived file inside the libraries directory found in the root Arduino IDE directory
To test your physical connection to the radio, and to ensure you are able to #include the library, would suggest you try the example sketch that is included in the library.
